6 Service and maintenance
Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.
The ball bearings used are greased for life. When the
machine has been in operation for a longer period of
time, we recommend to hand the machine in at an
authorised MAFELL customer service shop for
inspection.
6.1 Machine
The machine must be regularly cleaned off deposited
dust. When doing so, you should clean the ventilation
openings on the motor with a vacuum cleaner.
Only use our special grease, order No. 049040 (1 kg
tin) for all greasing points.
The saw wires used on the machine must be
regularly checked as sharp tools improve the cutting
quality. Replace worn or blunt saw wires.
Resharpening the saw wire is not possible.
6.2 Drive and guide wheel
The strain on the wheels is particularly high. They
must be replaced if they exhibit visible grooves (see
chapter 4.5 Change of drive wheel and guide wheel,
page 24).
6.3 Reamer
The scrapers keep the groove base of the drive and
deflection wheel clean. They must be checked on a
regular basis. They must be replaced if they are worn
or defective (see chapter 4.6 Change of scraper,
page 25).
6.4 Storage
If the machine is not used for a longer period of time,
it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
